Does a complex world need simpler rules?
Absolute rules (if X, then Y) work with the grain of human nature. We feel far more guilt running a red light than breaking a speed limit. Notice that almost all religious laws are absolute: no food is half kosher; it is or it isn’t. No Old Testament prophet proposed something as daft as the French 35-hour ‘working-time directive’: they invented the Sabbath instead.
Interesting point of view. The problem indeed stems from the difficulty to agree on absolute rules. That’s why we compromise.
